Question

The more positive the packing fraction of an element, the more stable should be nucleus.

• A. True
• B. False

Answer 1

The correct option is B False

From figure it can be seen that, stability of nucleous depens upon ration of n/p, if repulsive forces are higher then nucleous will be unstable and if they are lesser than nucleous will be stable. Since, in close packing, the protons come together so, repulsion also increases. Therefore, the more positive the packing fraction of an element, the more $unstable$ the nucleus is.

Hence, the given statement is false.
